Should I get Nifty Knitting?

When I first got the pack I went overboard and got my sim to knit way too many things. I realized I could only sell on plopsy, on average, one item every 2-3 days so it was much slower than I anticipated. I thought my sim could earn a living with knitting alone, but I ended up getting a part time job for her, and knitting on the side. Overall it's a pretty neat pack, and plopsy comes in handy for other things, even if your sim doesn't knit. I love the succulent plants in the game so the hanging planters were one of the draws for me to get the pack. That, plus the animation of cats playing with yarn is adorable! And just like wood working, I get a kick out of the poorly crafted items. I like hanging on to those and displaying them in my sims' homes.
